After playing around with Freetouch to make a knitted fabric switch, it was found that the sensor reading varied depending on the type of interactions. For example, prodding the fabric resulted in a much lower sensor reading than grabbing the fabric. Based on this observation, I played around with how to use Freetouch and knitted …
A handy-dandy portable device for testing e-textile sensors on the fly. Sometimes your electronics workspace and your textiles workspace are not the same places. You want to make multiple samples and test them, but then you have to carry your whole electronics prototyping kit (laptop, breadboard, crocodile clips, Arduino etc) and do all the setup. …

Ever tried to get out of bed quietly at night only to trip over something and wake up the whole house? Motion sensing night lights installed discreetly under your bed provide low-level light bright enough to guide you around those stray LEGO bricks but dim enough so you’re not woken up fully. As well as …
The A1230 is a dual-channel, bipolar switch with two Hall-effect sensing elements, each providing a separate digital output for speed and direction signal processing capability. The Hall elements are photo lithographically aligned to better than 1 µm. maintaining accurate mechanical location between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch …

Introduction Besides looking damned good on an otherwise bland and ordinary desk, this project is about more than just being attention grabbing eye candy. It’s about demonstrating a small portion of our single board computer capabilities by hooking up a color sensor, RGB light strip, and enclosing it in a nice looking wooden enclosure. We’re …

The SHT15 is a digital humidity sensor that outputs a fully calibrated humidity reading. And… because what we are measuring is actually relative humidity, and relative humidity being relative to temperature, the SHT15 has a builtin digital thermometer. This makes things much easier to work with than sensors without a thermometer onboard. You can pick …
The VL6180X is the latest product based on ST’s patented FlightSense™technology. This is a ground-breaking technology allowing absolute distance to be measured independent of target reflectance. Instead of estimating the distance by measuring the amount of light reflected back from the object (which is significantly influenced by color and surface), the VL6180X precisely measures the …

Note: When referring to Arduino below, this works in the same way on the emonTx which is arduino-based. The DS18B20 is a small thermometer with a built in 12bit ADC; it can be easily connected to Arduino digital input. The sensor communicates over a one-wire bus and requires little in the way of additional components. …

As part of the CanSat Primary Mission, we need to measure temperature. For this our starter kit has given us an Arduino Uno R3 micro-controller, as well as some resistors and an NTCLE101E3 NTC Thermistor. The thermistor is a special kind of resistor that changes its resistance with temperature. In our case we have an …
Origami is the traditional Japanese art of paper folding. In this project, with a little help from an Arduino, you can bring your origami into the 21st century and make it an interactive art! The result shown here uses Bare Conductive paint to give an origami flower proximity sensing powers. When you put your hand …
High-precision air quality monitors are normally very expensive, but Tim Dye of Sonoma Technology is on a mission to change that. He’s been working with Michael Heimbinder and habitatmap.org to create a low-cost sensor system that when designed properly and integrated into a software platforms can provide valid data. AirCasting is a platform for recording, mapping, …
